Heavy rain, thunderstorms likely tonight into Thursday

An approaching strong cold front, and associated mid and upper level disturbance, will bring heightened chances for rain into the area from tonight into Thursday morning. However, the event will be made more significant by a plume of moisture, surging northward along and ahead of the frontal boundary. Forecast models indicate a strengthening low level jet stream and transport of this moisture. Precipitable water values (the amount of water in the atmosphere) will be high — in the 95th percentile for October.

The moisture will begin surging northward later this afternoon and evening. Forecast models indicate the best lift for precipitation will remain to our west until the latter part of the afternoon. At that point, from west to east, chances for showers and thunderstorms will increase. Initially, downpours will be scattered. But over time tonight, the support for heavy rain will expand and moisture will continue surging northward. Rain will develop from southeast to northwest, with widespread heavy rain likely throughout the area overnight.
